Receiver power supply
A wide range of rechargeable four-cell and fi ve-cell NiMH
batteries varying in capacity is available for use as the
receiver power supply. If you are using digital servos
we recommend that you use a fi ve-cell (6 V) pack of
generous capacity. If your model is fi tted with a mixture of
digital and analogue servos, it is important to check the
maximum permissible operating voltage of all the types.
The PRX unit, Order No. 4136, provides a stabilised
receiver power supply with a user-variable voltage from
one or two receiver batteries; see Appendix.
For reasons of safety battery boxes or dry cells should
never be used.
The voltage of the airborne power supply is displayed on
the optional Smart-Box screen while the model is fl ying:
RX DATAVIEW

L.R-VOLT:04.5V
S–QUA100%S–dBM–030dBM
SENSOR1 :00.0V 00°C
SENSOR2 :00.0V 00°C
If the voltage falls below the pre-set warning threshold -
3.8 Volt as standard, but variable in the Telemetry menu;
see page 115 - a visual and audible low-voltage warning
is triggered.
Nevertheless it is important to check the state of the
batteries at regular intervals. Don’t put off charging
the batteries until the warning signal is triggered.
Note:
Please refer to the main Graupner FS catalogue or visit
the Internet site at www.graupner.de for full details of
batteries, chargers, measuring equipment and battery
monitor units.
Charging the receiver battery
The charge lead, Order No. 3021, can be connected
directly to the NC receiver battery for charging. If the
battery is installed in a model and you have installed one
of the following switch harnesses: Order No. 3046, 3934
or 3934.1 or 3934.3, the battery can be charged via the
separate charge socket, or the charge socket which is
built into the switch. The switch on the switch harness
must be left at the “OFF” position for charging.

General notes on battery charging
Observe the recommendations provided by the
charger manufacturer and the battery manufacturer
at all times.
Keep to the maximum permissible charge current
stated by the battery manufacturer.
The maximum charge current for the transmitter
battery is 1.5 A. Limit the charge current to this value
on the charger.
If you wish to charge the transmitter battery at a
current higher than 1.5 A, you must fi rst remove the
pack from the transmitter, otherwise you risk dama-
ging the circuit board through overloading the con-
ductor tracks, and / or overheating the battery.
Carry out a series of test charges to ensure that the
automatic charge termination circuit works correctly
with your battery. This applies in particular if you
wish to charge the standard Ni-MH battery using an
automatic charger designed for Ni-Cd batteries.
You may need to adjust the Delta Peak trigger volta-
ge, if your charger provides this option.
Do not discharge the battery or carry out a battery
maintenance program via the integral charge socket.
The charge socket is not suitable for this application.
Always connect the charge lead to the charger fi rst,
and only then to the transmitter or receiver battery.
Observing this rule eliminates the danger of acciden-
tal short-circuits between the bare contacts of the
charge lead plugs.
If the battery becomes hot when on charge, it is time
to check the pack’s condition. Replace it if necessary,
or reduce the charge current.
Never leave batteries unsupervised when on
charge.
Environmental protection notes
Important information on the disposal of dry and
rechargeable batteries:
The German Battery Order places a legal requirement
on every consumer to return all used and exhausted
dry cells and rechargeable batteries. It is prohibited to
dispose of these items in the ordinary domestic waste.
At no charge to the user, old dry and rechargeable
batteries can be surrendered at local authority collec-
tion points, Graupner retail outlets, and any other shop
where dry and rechargeable batteries of the same type
are sold. You can also send batteries supplied by us to
the following address - with adequate pre-paid postage
- for disposal:
Graupner GmbH & Co. KG
Service: Gebrauchte Batterien (Used batteries)
Henriettenstr. 94 - 96
D-73230 Kirchheim unter Teck
You can make an important contribution to environmen-
tal protection in this way.

Program description: Trainer system
Trainer Mode
Connecting two transmitters for trainer mode operations
The mx-10 HoTT transmitter can be combined by wi-
reless means to form a Trainer system. Here, the second
transmitter must not be the mx-10 HoTT also, every
other HoTT transmitter with the possibility of wireless
Trainer operation is suitable. Therefore please read the
manual of your HoTT system!
Switching from the normal operating mode to the trans-
mitters teacher or student mode is done by the mode
switch on the left top side of the transmitter:
To change the mode, move the mode switch on the
transmitter in the desired position, press and hold the
BIND-button and then switch on the transmitter.

Important Note:
The following description is based on the time of
printing this manual current version 1.00 of the
transmitter software, and is equally valid for all
previous Software versions. It can not be excluded
that after the next update, the following description
will not be correspondend with the functionality of
the HoTT Trainer system.
Teacher transmitter settings mx-10 HoTT
The trainer model must be programmed completely,
i. e. with all its functions including trims and any mixer
functions in the mx-10 HoTT Teacher transmitter. This
means that it must be possible to control the trainer
model fully, without restriction, by the Teacher trans-
mitter. But, at the conclusion of these preparations,
the trainer model must be bound to the Pupil trans-
mitter. A detailed description of the binding process can
be found on page 106 and 109.
Note when using the mx-10 HoTT as pupil transmitter:
the mx-10 HoTT binding procedure can only be done
in „normal“ mode. Before using the transmitter in Pupil
mode, bind the receiver in mode „normal“, then switch to
the mode „pupil“. In addition, no mixer may be activated,
move the jumper in the middle position „NO MIX“, see
also page 105.
All fi ve transmitter control functions of the Teacher trans-
mitter “T” can be transferred to the pupil transmitter “P”.
The stick mode of the pupils transmitter may deviate
from the teacher transmitter, because the stick mode
and mixers will be transfered from the teachers transmit-
ter. Therefore the teachers transmitter must be properly
programmed for the training model with all functions and
mixers.
After the pupils transmitter is bound to the trainer model,
set the mx-10 HoTT in the teacher mode. To change
the mode, move the mode switch on the transmitter in
the „teacher“ position, press and hold the BIND-button
and then switch on the transmitter.
Now press the BIND-button of the puplis transmitter:
mx-10 HoTT: press and hold
In the following the student programming for the mx-
12/16/20 HoTT is described. Please read also the
instructions for your remote control system!
Switch on the transmitter, and use the arrow buttons of
the left or right-hand four-way button to leaf through on
both transmitters to the “Trainer” menu point of the multi-
function menu. (The trainer model’s receiving system,
previously bound to the Pupil transmitter, does not need
to be switched on during the following procedure.):
